Clinical characteristics and outcomes of 176 patients with acute necrotizing mediastinitis: A retrospective cohort study / 中国胸心血管外科临床杂志

@#Objective To investigate the etiology, symptoms, diagnosis, surgical treatment, and outcomes of acute necrotizing mediastinitis (ANM) in order to guide future diagnosis and treatment of ANM. Methods The clinical data of patients with ANM referred to West China Hospital, Sichuan University from March 2012 to April 2021 were retrospectively analyzed. The etiology, clinical manifestations, demographic characteristics, bacterial culture results, surgical approach and prognostic factors of these patients were summarized. Results A total of 176 patients were enrolled in this study. The median age was 60 ( 0-84) years. There were 124 (70.5%) males and 52 (29.5%) females. The most common origin of infection was neck (n=66, 37.5%). The most common symptom was fever (n=85, 48.3%). Streptococcus constellatus represented the most common pathogens in secretion culture. Surgical treatment was administered to 119 (67.6%) patients through different approaches, including 54 (30.7%) patients of cervical approach, 9 (5.1%) patients of thoracotomy, 18 (10.2%) patients of video-assisted thoracoscopic surgery (VATS), 7 (4.0%) patients of cervical combined with thoracotomy, 30 (17.0%) patients of cervical combined with VATS, and 1 (0.6%) patient of subxiphoid approach. Among this cohort, 144 (81.8%) patients were cured, while 32 (18.1%) patients died. Age-adjusted Charlson comorbidity index (OR=2.95, P=0.022), perioperative sepsis (OR=2.84, P=0.024), and non-surgical treatment (OR=2.41, P=0.043) were identified as independent predictors of poor outcomes. Conclusion For patients with corresponding history and manifestations of ANM, it is crucial to go through imaging examination to confirm the presence of an abscess and guide the selection of surgical approach. Once the diagnosis of ANM is made, it is imperative to promptly perform surgical intervention for effective drainage. Our study highlights the significance of age-adjusted Charlson comorbidity index, perioperative sepsis and surgical treatment in predicting patients’ outcomes.

Clinical characteristics of patients with puerperal schizophrenia / 四川精神卫生

BackgroundWomen may develop severe symptoms of stress disorder following childbirth， which may be exposed to a risk of developing mental health problems， and even lead to the recurrence of the illness in female patients with schizophrenia， while comparatively limited research has been undertaken concerning the clinical characteristics and treatment of puerperal schizophrenia in China. ObjectiveTo explore the clinical characteristics of puerperal schizophrenia， so as to provide references for the clinical treatment. MethodsA total of 24 patients with puerperal schizophrenia who were hospitalized in the female ward of adult psychiatry department of the Affiliated Brain Hospital of Guangzhou Medical University from 2012 to 2020 and met the Diagnostic and Statistical Manual of Mental Disorders， fourth edition （DSM-IV） diagnostic criteria for schizophrenia were included as puerperal group. Another 48 non-puerperal women with schizophrenia were concurrently enrolled as control group. Then the basic data， scores on Positive and Negative Symptom Scale （PANSS） and the discharge medication were recorded. ResultsThe percentages of newly onset and positive family history of psychosis in puerperal group were larger than those in control group， with statistical significance （χ2=9.321， 5.240， P<0.05 or 0.01）. Puerperal group scored higher on PANSS excitement factor （t=-2.220， P<0.05） and lower on negative factor （t=3.377， P<0.01） compared with control group. In terms of discharge medication， puerperal group reported a higher dosage of antipsychotic drugs （t=-2.095， P<0.05）， and a larger proportion of combined use of benzodiazepines or antidepressants （χ²=21.316， 5.114， P<0.05 or 0.01） compared with control group， with statistical significance. ConclusionPatients with puerperal schizophrenia display increased ratings of excitement symptoms and decreased ratings of negative symptoms， which necessitates the use of high doses of antipsychotic drugs， and combined use of benzodiazepines and antidepressants.

Fitting Degrees of Animal Models of Diarrhea-irritable Bowel Syndrome with Clinical Characteristics of Western Medicine and Traditional Chinese Medicine / 中国实验方剂学杂志

Diarrhea-irritable bowel syndrome （IBS-D） is one of the common functional bowel diseases in clinical practice. Since it pathogenesis is complex and has not been fully elucidated， effective treatment methods remains to be developed for this disease. Establishing the animal models of IBS-D in accordance with the clinical characteristics of traditional Chinese medicine （TCM） and Western medicine helps to reveal the pathogenesis of this disease and improve the treatment plan. The fitting degree of an animal model with clinical characteristics is an indicator to evaluate the effectiveness of the animal model in simulating the disease characteristics of Western medicine and the syndromes of TCM based on the latest diagnostic standards. By reviewing the relevant articles about the animal models of IBS-D， we discovered that rats were the preferred animals for modeling， and the models were mainly induced by single factors， double factors， or the combination of multiple factors. The established animal models mainly present symptoms or signs associated with visceral hypersensitivity or/and gastrointestinal motility abnormalities. The single factor-induced rat models of IBS-D had high fitting degrees with the clinical characteristics of Western medicine but low fitting degrees with the TCM syndromes. The animal models induced by two or more factors had high but varied fitting degrees with the clinical characteristics of Western medicine. In addition， the animal models of IBS-D considering TCM syndromes mainly focuses on the syndrome of liver depression and spleen deficiency， and few models were established for the syndromes of spleen-kidney Yang deficiency， spleen-stomach dampness-heat， spleen deficiency and dampness excess， and cold and heat in complexity. Therefore， it is essential to improve the existing or develop new animal models of IBS-D in the future， so as to provide more tools for deciphering the mechanisms of TCM and Western medicine and developing treatment methods for this disease.

Clinical Characteristics and Potential Risk Factors Analysis of Liver Injury Related to Epimedii Folium Preparation / 中国实验方剂学杂志

ObjectiveThis paper aims to analyze the clinical characteristics and medication rationality of liver injury related to Epimedii Folium preparation （EP） and explore the possible risk factors of liver injury， so as to provide a reference for the safe clinical application of Epimedii Folium （EF）. MethodA retrospective analysis was conducted on liver injury cases related to EP from 2012 to 2016. ResultThe number of reported liver injury cases and the proportion of severe cases related to the use of EP show an increasing trend， indicating the objective existence of liver injury caused by EP. There are more cases of liver injury related to EP in women than in men， with an onset age range of 15-91 years old and a median onset age of 60 years old （median onset ages for men and women are 59 and 60 years old， respectively）. The time span from taking EP alone to the occurrence of liver injury is 1-386 days， with a median of 38 days. The time span from taking both EP and Western medicine to the occurrence of liver injury is 1-794 days， with a median of 34 days. EF-related liver injury preparations are mostly composed of traditional Chinese medicines that promote immunity and tonify the liver and kidney， indicating that immune stress in the body may be the mechanism of liver injury caused by the use of EP alone or in combination. There is no increasing trend of toxicity with time or dose in the liver injury caused by EP. By further exploring its risk factors， it is found that patients have unreasonable medication methods such as excessive dosage， repeated use， and multi-drug combination， which may also be one of the important risk factors for EF-related liver injury. ConclusionEP has a certain risk of liver injury and should be emphasized in clinical diagnosis and treatment. Immune stress may be the mechanism of liver injury caused by EP， and in clinical use， it is necessary to be vigilant about the risk of liver injury caused by unreasonable use and combined use with Western medicine.

A descriptive cross-sectional study was conducted with the purpose of clinically and epidemiologically characterizing anal HPV infection in patients who attended the Benign Orificial Pathology Consultation of the Coloproctological Unit at the Dr. "Antonio María Pineda" Central University Hospital, during the period March 2022 -February 2023, by selecting 288 patients whose average age was 47.09 ± 14.61 years, being the 41-50 years old group (29.17%) and the 51-60 years old group (19.44%) the most affected groups by pathologies of the anal region, with a predominance of male (54.17%). The sociodemographic characteristics with the highest frequency included married (48.61%) and single (47.22%); secondary level of education (44.44%) and traders (18.05%) and housewives (15, 28%) as predominant occupations. The risk factors were represented by onset of sexual intercourse between 16-20 years of age (65.28%), heterosexuality (91.67%), 22.22% reported having anal sex and 5.56% oral sex. Likewise, 5.56% were reported with a history of genital HPV and 4.17% were HIV positive. In addition, 48.61% stated not to use condoms. The initial clinical diagnosis included hemorrhoidal disease (30.55%), anal fistula (25%) and anal fissure (18.05%), and one patient (1.39%) with anal HPV infection. Anal cytology results showed 8.33% flat epithelial cells with cytopathic changes suggestive of HPV infection and 1.39% squamous cells with cytopathic changes suggestive of HPV infection: 50% mild inflammatory negative for malignancy and 33.33% flat epithelial cells without atypia. In conclusion, the anal cytology investigation should continue to determine the actual frequency of anal HPV infection. (AU)

Características epidemiológicas y clínicas autorreportadas en pacientes con obesidad y COVID-19: un estudio de corte transversal / Epidemiological and clinical characteristics self-reported in patients with obesity and COVID-19 disease: a cross-sectional study

RESUMEN INTRODUCCIÓN En Argentina, la obesidad en adultos es una problemática con una prevalencia media de 25,4%. En la relación entre COVID-19 y obesidad, se observa mayor prevalencia de sobrepeso/obesidad y enfermedad severa entre los pacientes con COVID-19. Por ello, el objetivo del estudio fue conocer las características clínicas y epidemiológicas en pacientes con diagnóstico de obesidad sobrevivientes a la infección por SARS-CoV-2. MÉTODOS Se realizó un estudio observacional descriptivo y analítico de corte transversal. Se aplicó una encuesta autoadministrada. RESULTADOS La mediana de edad fue 41 años, y hubo un 69,9% de mujeres. Los síntomas de presentación más prevalentes fueron astenia (86,7%), anosmia (64,5%) y tos (64%). Con respecto a los síntomas persistentes luego de las 12 semanas del diagnóstico, los más prevalentes fueron astenia (52,9%), trastornos de sueño (32,4%) y falta de concentración/memoria (31,7%). Hubo mayor riesgo en mujeres (OR: 2,86; IC95%: 2,23-3,67) con obesidad (OR: 1,58; IC95%: 1,16-2,16). La enfermedad grave en obesos fue casi el triple comparado con no obesos (15,7% vs. 5,4%; p<0,001). DISCUSIÓN Los pacientes obesos mostraron síntomas de presentación que orientan a un estado inflamatorio sistémico, con disnea y tos más frecuentes, y tienen mayor prevalencia de enfermedad grave y neumonía, así como mayor riesgo de desarrollar síntomas persistentes, sobre todo si las personas son mujeres y sedentarias.

ABSTRACT INTRODUCTION In Argentina, obesity in adults is a problem with an average prevalence of 25.4%. The relationship between COVID-19 and obesity shows a higher prevalence of overweight/obesity and severe disease among patients with COVID-19. Therefore, the objective of the study was to know the clinical and epidemiological characteristics of patients diagnosed with obesity who survived SARSCoV- 2 infection. METHODS A descriptive and analytical cross-sectional observational study was carried out. A self-administered survey was applied. RESULTS The median age was 41 years and 69.9% were women. The most prevalent presenting symptoms were asthenia (86.7%), anosmia (64.5%) and cough (64%). Regarding persistent symptoms 12 weeks after diagnosis, the most prevalent ones were asthenia (52.9%), sleep disorders (32.4%) and lack of concentration/memory (31.7%). The risk was higher for women (OR: 2.865; CI95%: 2.23-3.67) with obesity (OR: 1.58; CI95%: 1.16-2.16). Severe disease in obese was almost threefold that in non-obese patients (15.7% vs. 5.4%; p<0.001). DISCUSSION Obese patients showed presenting symptoms that point to a systemic inflammatory state, with dyspnea and cough being more common, and have a higher prevalence of severe disease and pneumonia, as well as a higher risk of developing persistent symptoms, especially if they are women and sedentary.

Relationship between quality of life and sociodemographic, clinical and lifestyle characteristics of patients undergoing hemodialysis

Introduction: In chronic diseases, QoL depends on several factors such as the type and duration of the disease, its treatment and side effects, the severity of symptoms, medication effects, patient age, limitations and self-care capacity. In chronic kidney disease it has also become a measure of health outcome.Objective: assess the association between QoL and socioeconomic, lifestyle and clinical factors of patients on HD.Methods: This is a cross-sectional epidemiological census, carried out among 1,024 patients on hemodialysis from all hemodialysis units at the metropolitan region in the Espirito Santo's, Brazil . Sociodemographic, lifestyle and clinical characteristics data were used. QoL was assessed using the Short-Form health Survey-36 (SF-36). Data were analysed by multiple linear regression.Results: The best QoL was represented by mental health (72.16) and the worst QoL by the physical aspect (26.78). After multiple linear regression, predictors of QoL were identified, with emphasis on males, a predictor of better QoL for 5 of the 8 domains and the summaries of the physical and mental components. Education, associated with 5 domains, gives greater reference to income. Physical activity was a predictor of 7 of the 8 QoL domains and the summary of the physical component. Among the clinical variables, the number of complications is associated with 7 of the 8 domains and summaries of the physical and mental components.Conclusion: Male sex is highlighted as a predictor of better physical and mental health and elderly people with better mental health, despite the impairment in physical health. The absence of physical activity is associated with worse physical and mental health. Clinically, having 3 or more intradialytic complications was associated with worse physical and mental QoL

Clinical Characteristics and Diagnostic Methods of Pulmonary Mucormycosis / 中山大学学报(医学科学版)

ObjectiveTo summarize the clinical features and prognosis of pulmonary mucormycosis （PM） in southern China， and to explore the diagnostic value of metagenomic next generation sequencing （mNGS） in PM. MethodsThe clinical manifestations， diagnosis， treatment and prognosis of patients diagnosed with PM in The First Affiliated Hospital of Sun Yat-sen University from January 1， 2019 to January 31， 2022 who had undergone mNGS detection in lung tissue or alveolar lavage fluid were collected retrospectively. A total of 14 patients with PM were included， including 4 patients with confirmed diagnosis and 10 patients with clinical diagnosis. ResultsAll patients had underlying medical conditions， with hematological malignancies and diabetes being the most common. The most common symptoms were fever （n = 10）， cough （n = 9） and shortness of breath （n = 9）. Consolidation was the most common sign of chest CT， followed by mass， mostly with cavity. On laboratory tests， decreased CD4+T lymphocytes， elevated CD8+T lymphocytes， and decreased CD4+/CD8+ ratio， and presentation with pleural effusion indicate poor prognosis. The positive rate of mNGS diagnosis was 78.5%， which was significantly higher than that of histopathology （50%）， fungus rapid fluorescence staining （61.5%） and fungal culture （23.1%） of bronchoalveolar lavage fluid. ConclusionsPulmonary mucormycosis is more likely to occur in patients with underlying diseases or who are immunocompromised. The clinical manifestations lack specificity. The low CD4/CD8 ratio and presentation of pleural effusion on CT imaging indicate poor prognosis of patients. mNGS is a rapid， convenient and sensitive method for the diagnosis of PM， which has advantages in the diagnosis of pulmonary mucormycosis.

To analyze the clinical characteristics of elderly patients with papillary thyroid carcinoma / 中华老年医学杂志

Objective:To analyze the clinical characteristics of elderly patients with papillary thyroid cancer(PTC)by age grouping.Methods:The patients were divided into three groups according to age at diagnosis: old(≥60 years, 90 cases), middle(40-59 years, 359 cases)and young patients(<40 years, 203 cases). The clinical data of 652 patients with PTC who were admitted to the Department of Thyroid Surgery of Beijing Hospital from December 2019 to December 2021 were retrospectively analyzed.The patients were divided into elderly group(≥60 years old, 90 cases), middle-aged group(40-59 years old, 359 cases)and young group(<40 years old, 203 cases). The clinical characteristics, ultrasound characteristics and invasion-related factors of patients in different groups were analyzed by statistical methods.Results:Compared with the young and middle-aged group, the elderly patients with PTC had a higher proportion of microcarcinoma(75.6%, 75.2%, 61.4%, χ2=13.054, P=0.001), less cervical lymph node metastasis(24.4%, 34.3%, 58.1%, χ2=41.650, P<0.001), and lower proportion of metastatic lymph nodes(0.08, 0.14, 0.24, χ2=40.618, P<0.001). There was no significant difference in tumor location and extra glandular invasion among the three age groups(35.56%, 36.2%, 38.4%, χ2=0.959, P=0.545). Conclusions:Compared with the young and middle-aged groups, PTC showed low invasiveness in the elderly population.In addition to surgical treatment, for elderly patients with low-risk clinical characteristics, it is worth performing a further study on whether careful observation or palliative treatment can be selected after comprehensive evaluation.

Clinical characteristics and virus identification of 4 cases of monkeypox confirmed in Zhejiang province / 中华临床感染病杂志

Objective:To analyze the clinical characteristics of monkeypox patients.Methods:The clinical data and laboratory findings of 4 patients with monkeypox patients diagnosed at Yiwu Central Hospital in July 2023 were analyzed. Herpes fluid and skin tissue samples were collected, the viruses were isolation and cultured in African green monkey kidney cells (Vero) and identified with whole gene sequencing.Results:All four patients were male, aged 24-35 years. All patients had male-to-male behavior within 21 days before onset of the disease. Among them, one patient has AIDS and one patient has syphilis. Four patients presented with perineal skin lesions with itching, and 3 patients were found to have enlarged lymph nodes upon admission. Laboratory testing: lymphocyte abnormality (4.57×10 9/L) in 1 case; increased procalcitonin (0.25 ng/mL) in 1 case; elevated IL-10 levels ( 7.11 ng/L and 9.42 ng/L) in 2 cases; increased IL-6 (66 ng/L) and IL-4 (3.24 ng/L) in 1 case, respectively. One case had abnormal myocardial zymogram with a elevated lactate dehydrogenase level of 313 U/L. The monkeypox virus was isolated from lesion tissue and herpes fluid, and the whole gene sequencing identified it as the B. 1.3 subtype of the IIb evolutionary branch, exhibiting typical pathological effects on Vero cells. Conclusion:The clinical manifestations of the 4 monkeypox patients confirmed in Zhejiang province are mild, patients had a definitive history of male-to-male sexual behavior and the virus strains belong to the B. 1.3 lineage of the IIb evolutionary branch.

Risk assessment for patients with severe acute pancreatitis complicated by clinically significant bleeding / 中华肝胆外科杂志

Objective:To analyze the risk factors of clinically significant bleeding in patients with severe acute pancreatitis (SAP).Methods:The clinical data of SAP patients who were managed at Changhai Hospital affiliated to Naval Medical University from January 1, 2014 to October 31, 2022 were retrospectively analyzed. Twenty-nine SAP patients with clinically significant bleeding were classified to form the bleeding group. There were 23 males and 6 females, aged (56.25±14.01) years old. Another 116 SAP patients with similar general data but with no clinically significant bleeding during the same hospitalization period were included to form the non-bleeding group based on a ratio of 1∶4. There were 94 males and 22 females, aged (56.14±13.96) years old in this non-bleeding group. The general data, modified CT severity index (MCTSI), bedside index for severity of acute pancreatitis (BISAP) and other clinical data of the two groups were collected to determine the risk factors of bleeding in SAP patients.Results:Of the 29 patients with bleeding, 6 had gastrointestinal bleeding, 14 had intra-abdominal bleeding, and 9 had mixed bleeding sites, 15 were cured and discharged, and 14 died. All the 29 SAP patients with bleeding received treatment using drugs. In addition, 8 patients underwent successful hemostasis using digital subtraction angiography, 3 underwent successful endoscopic hemostasis, 2 underwent successful surgical hemostasis, and 2 underwent successful conservative drug hemostasis. Multivariate logistic regression analysis showed that SAP patients with higher MCTSI ( OR=1.824, 95% CI: 1.187-2.802), longer prothrombin time (PT) ( OR=3.431, 95% CI: 1.470-8.007) and higher BISAP ( OR=2.286, 95% CI: 1.054-4.957) had an increased risk of bleeding (all P<0.05). Conclusion:The prognosis of SAP patients was compromised with bleeding. High MCTSI, prolonged PT, and high BISAP were independent risk factors for bleeding in SAP patients.

Clinical characteristics of 86 children with Beh?et′s disease / 中华风湿病学杂志

Objective:To analyze the clinical characteristics of pediatric patients with Beh?et′s disease.Methods:The clinical characteristics of 86 newly diagnosed children with Beh?et′s disease admitted to the rheumatology department of Beijing Children′s Hospital from July 2015 to December 2020 were analyzed retrospectively. Statistical product and service solutions (SPSS) 26 was used for statistical analysis. The normal distribution of measurement data is expressed in Mean± SD, and the non normaldistribution of measurement data was expressed in median(minimum, maximum). The counting data was expressed in frequency (cases) and percentage. Results:There was no gender difference in the incidence of Beh?et′s disease in 86 children.The age of onset was 0.1~15.9 years, with an average of (7±4) years, and the age of diagnosis was 1.3~16.6 years, with an average of (10±4) years.The course of disease from onset to diagnosis was 0.5~168 months, with a median course of 21 months. Among 86 cases, 52 cases (60.5%) showed the most common oral ulcer at the onset, followed by 19 cases (22.1%) with fever. In terms of clinical manifestations: the most common clinical manifestation was oral ulcer in 82 cases (95.3%), followed by fever in 58 cases (67.4%), and gastrointestinal symptoms in 44 cases (51.2%). The common manifestation of digestive system involvement was abdominal pain and diarrhea. Ten cases (11.6%) had ocular symptoms, 13 cases (15.3%) had vascular involvement, and 3 cases (3.5%) had pulmonary involvement. Fourteen cases (16.2%) had family history. Fourty seven patients (54.7%) had elevated leukocyte, 65 patients (75.6%) had elevated CRP and 72 patients (83.7%) had elevated ESR.Conclusion:Beh?et′s disease in children is usually insidious in onset and infants may suffer from this disease. Oral ulcer is the most common clinical manifestation, followed by fever. For patients with fever of unknown cause, Beh?et′s disease should be noted. In terms of involvement of important organs, digestive tract involvement is more common in childhood, followed by large blood vessels and eyes.

Clinical characteristics of cryptococcal meningitis patients with anti-granulocyte-macrophage colony-stimulating factor autoantibodies / 中华传染病杂志

Objective:To investigate the clinical characteristics and prognosis of cryptococcal meningitis patients with anti-granulocyte-macrophage colony-stimulating factor (GM-CSF) autoantibodies.Methods:A total of 216 non-acquired immunodeficiency syndrome (AIDS) related cryptococcal meningitis cases with positive cultures of Cryptococcus, hospitalized at Huashan Hospital, Fudan University during January 2014 and December 2021, were retrospectively included. The serum anti-GM-CSF autoantibodies were detected by enzyme linked immunosorbent assay, and the clinical characteristics and prognosis were compared between patients with and without anti-GM-CSF autoantibodies. Statistical comparisons were mainly performed using the chi-square test or Fisher′s exact test. Cox proportional-hazards model was used to analyze the risk factors associated with prognosis. Results:Among 216 enrolled patients, 23 patients were positive of anti-GM-CSF autoantibodies, with a positive rate of 10.6%. Among 23 patients, seven cases were infected with Cryptococcus gattii, and 16 cases were infected with Cryptococcus neoformans. In the group with positive anti-GM-CSF autoantibodies, 30.4%(7/23) of the patients were infected with Cryptococcus gattii, which was higher than that of 1.6%(3/193) in the group with negative anti-GM-CSF autoantibodies, and the difference was statistically significant ( χ2=38.82, P<0.001). In the group with positive anti-GM-CSF autoantibodies, 30.0% (6/20) had mass lesions with a diameter greater than three centimeters in the lungs, and the one-year all-cause mortality rate was 50.0% (10/20), which were both higher than those of 3.4%(5/145) and 16.1% (29/180) in the negative group, respectively. The differences were both statistically significant (both Fisher′s exact test, P<0.01). Age≥60 years (hazard ratio ( HR)=4.146, P=0.002), predisposing factors ( HR=3.160, P=0.021), epilepsy ( HR=6.129, P=0.002), positive anti-GM-CSF autoantibodies ( HR=2.675, P=0.034), white blood cell count of cerebrospinal fluid (CSF)<100 ×10 6/L ( HR=2.736, P=0.039), the titers of cryptococcal capsular polysaccharide antigen of CSF≥1∶1 280 ( HR=4.361, P=0.009) were independent risk factors for one-year all-cause mortality in patients with cryptococcal meningitis. Conclusions:In non-AIDS related cryptococcal meningitis patients, the positive rate of serum anti-GM-CSF autoantibodies is as high as 10.6%. Patients with anti-GM-CSF autoantibodies could be infected with both Cryptococcus neoformans and Cryptococcus gattii, and they have higher proportion of lung mass lesions than patients with negative anti-GM-CSF autoantibodies. The one-year survival rate decreases significantly in patients with anti-GM-CSF autoantibodies, which is an independent risk factor for the prognosis of cryptococcal meningitis.

Clinical characteristics and prognosis of bacterial liver abscess in patients with diabetes mellitus / 中华传染病杂志

Objective:To compare the clinical characteristics and prognosis of bacterial liver abscess in patients with or without diabetes mellitus (DM), to provide a reference for clinical diagnosis and treatment.Methods:Patients with bacterial liver abscesses hospitalized in Tongren Hospital, Shanghai Jiao Tong University School of Medicine from January 2016 to August 2021 were enrolled, and their clinical data were collected. The patients were divided into diabetic and non-diabetic groups for comparison according to whether they had comorbid DM. Statistical analysis was performed by chi-square test or Fisher′s exact test, and multivariate logistic regression analysis.Results:A total of 131 patients with bacterial liver abscesses were included, including 47 cases in the diabetic group and 84 cases in the non-diabetic group. The percentages of platelet count <100×10 9/L, C-reactive protein>10 mg/L, and total bilirubin>17.5 μmol/L were lower in the diabetic group than that in the non-diabetic group, and the differences were all statistically significant ( χ2=3.90, 6.44 and 5.56, respectively, all P<0.05). The percentage of multiple abscesses in the diabetic group was 10.6%(5/47), which was lower than 29.8%(25/84) in the non-diabetic group, and the difference was statistically significant ( χ2=6.24, P=0.012). The positive rate of pus culture for Klebsiella pneumoniae was 64.9%(24/37) in the diabetic group, which was higher than 41.5%(27/65) in the non-diabetic group, with a statistically significant difference ( χ2=5.13, P=0.023). The incidences of pleural effusion and abscesses at other sites in the diabetic group were 29.8%(14/47) and 10.6%(5/47), respectively, which were both higher than 14.3%(12/84) and 1.2%(1/84) in the non-diabetic group, respectively, and the differences were statistically significant ( χ2=4.55, Fisher′s exact test, both P<0.05). The proportion of hospital stays>21 d was 34.0%(16/47) in the diabetic group, which was higher than 16.7%(14/84) in the non-diabetic group, with a statistically significant difference ( χ2=5.15, P=0.023). DM (odds ratio ( OR)=2.654, 95% confidence interval ( CI) 1.020 to 6.907, P=0.046) and abscess maximum diameter>10 cm ( OR=11.045, 95% CI 4.493 to 27.154, P<0.001) were significant risk factors for hospital stay>21 d. Conclusions:Bacterial liver abscesses combined with DM are more common with single abscess, a higher rate of Klebsiella pneumoniae infection, and more likely to develop pleural effusions and abscesses at other sites. Liver abscesses>10 cm in maximum diameter and comorbid DM would prolong hospital stay.

Clinical characteristics and risk factors for severe disease of hemorrhagic fever with renal syndrome in underage patients / 中华传染病杂志

Objective:To analyze the clinical characteristics and risk factors for severe disease of hemorrhagic fever with renal syndrome (HFRS) in underage patients, and to construct the severe disease risk model.Methods:A total of 170 HFRS patients (<18 years old) from the Second Affiliated Hospital of Air Force Medical University (153 cases) and the Second Affiliated Hospital of Xi′an Jiaotong University (17 cases) from January 2009 to December 2021 were included. According to the severity of the disease, the patients were divided into mild and severe groups. Baseline demographic data, symptoms, signs, laboratory examination on admission and prognosis were analyzed between the two groups. Statistical comparisons were performed using the Mann-Whitney U test and chi-square test.Binary logistic regression was used to analyze the independent risk factors of patients with severe disease, and the severe disease risk model was built.The receiver operator characteristic curve was used to analyze the value of the risk model in predicting severity of disease. Results:Among the 170 underage patients, 132 (77.6%) were males, aged (14.9±3.1) years, including 124 cases in mild group and 46 cases in severe group. One hundred and sixty-nine cases (99.4%) had fever, 119 cases (70.0%) had headache, 106 cases (62.4%) had lumbago, 158 cases (92.9%) had skin and mucous congestion, and 101 cases (59.4%) had nausea and vomiting. Renal percussive pain was found in 139(81.8%) patients. The incidence of nausea and vomiting and bleeding of skin and mucosa in the severe group were 71.7%(33/46) and 67.4%(31/46), respectively, which were both higher than those in the mild group (54.8%(68/124) and 44.4%(55/124), respectively), and the differences were statistically significant ( χ2=3.97 and 7.12, respectively, both P<0.05). There were significant differences in platelet count, activated partial thromboplastin time (APTT), serum creatinine (SCr), aspartate aminotransferase, alanine aminotransferase, leukocyte count, total bilirubin and albumin levels between the two groups ( Z=-4.14, -4.04, -4.87, -3.90, -4.07, -2.60, -2.78 and t=2.50, respectively, all P<0.05). Binary logistic regression analysis showed that chemosis (odds ratio ( OR)=8.035, 95% confidence interval (95% CI) 2.946 to 21.916), SCr ( OR=1.010, 95% CI 1.006 to 1.015) and APTT ( OR=1.049, 95% CI 1.003 to 1.098) were the independent risk factors for severe HFRS in the underage patients. The risk model was constructed as: Logit(P)=-10.323+ 2.084×chemosis (no=0, grade Ⅰ=1, grade Ⅱ=2, grade Ⅲ=3)+ 0.010×SCr (μmol/L)+ 0.048×APTT (s). The area under the curve to predict severity of disease in underage HFRS patients was 0.868, with an optimal cut-off value of -4.39, with a sensitivity of 73.90% and a specificity of 91.10%. According to the internal verification of the data of the study based on the severe disease risk model, 34 out of 46 patients with severe disease were severe (sensitivity, 73.91%), 113 out of 124 patients with mild disease were mild (specificity, 91.13%). Conclusions:The clinical manifestations of the underage HFRS patients are not typical.The main manifestations are fever, headache and lumbago, nausea and vomiting, and the incidences of skin and mucous congestion and renal percussive pain are high.Chemosis, SCr and APTT are independent risk factors for severe disease in underage patients with HFRS. The severe disease risk model could effectively predict the severity of disease.

Clinical characteristics of patients with acquired immunodeficiency syndrome complicated with nontuberculous mycobacteria disease / 中华传染病杂志

Objective:To explore the clinical characteristics of acquired immunodeficiency syndrome (AIDS) complicated with nontuberculous mycobacteria (NTM) disease.Methods:The clinical data of 190 patients with AIDS complicated with NTM disease diagnosed by Shanghai Public Health Clinical Center, Fudan University from January 1, 2019 to December 31, 2021 were analyzed retrospectively. NTM diseases were divided into disseminated NTM disease group and non-disseminated NTM disease group. The independent sample t test, Mann Whitney U test and chi-square test were used for statistical analysis. Results:The 190 patients with AIDS complicated with NTM disease included 182 males and eight females. The age was (42±13) years old, and the first hospital stay was 15(6, 26) days. Pneumocystis carinii pneumonia was the most common co-infection in 12.1%(23/190) of patients, 87 cases (45.8%) were disseminated NTM disease. The clinical symptoms of patients were common in fever (55.8%(106/190)), cough (50.0%(95/190)), and expectoration (28.9%(55/190)). The proportions of fatigue (31.0%(27/87) vs 7.8%(8/103)), poor appetite (21.8%(19/87) vs 10.7%(11/103)) in the AIDS patients with disseminated NTM disease group were higher than those in the non-disseminated NTM disease group, and the differences were statistically significant ( χ2=16.99, P<0.001 and χ2=4.42, P=0.036, respectively). There was no significant difference in the proportions of deaths between AIDS patients with disseminated NTM disease and those without disseminated NTM disease (17.2%(15/87) vs 12.6%(13/103), χ2=0.80, P=0.371). The most common NTM species was Mycobacterium avium (67.1%(49/190)), followed by Mycobacterium kansasii (15.1%(11/190)). Hemoglobin ((90.3±23.9) g/L vs (110.1±24.2) g/L), albumin ((29.7±5.5) g/L vs (34.7±5.6) g/L), CD4 + T lymphocyte count (11(5, 30)/μL vs 52(16, 96)/μL) and CD8 + T lymphocyte count ((362±320)/μL vs (496±352)/μL) in the disseminated NTM disease group were lower than those in non-disseminated NTM disease group ( t=-5.63, P<0.001; t=-6.18, P<0.001; Z=-5.90, P<0.001; and t=-2.73, P=0.007, respectively), while procalcitonin (0.24(0.10, 0.77) μg/L vs 0.10 (0.04, 0.51) μg/L) was higher than that in the non-disseminated NTM disease group ( Z=-3.09, P=0.002), with statistical significance. The most common imaging features were lung patch and strip shadow (67.4%(128/190)). Conclusions:The most common type of AIDS patients complicated with NTM disease is disseminated NTM disease, and Mycobacterium avium is the most common NTM species. The clinical manifestations (fatigue, anorexia) and laboratory tests (hemoglobin, albumin, procalcitonin, CD4 + T lymphocyte count, CD8 + T lymphocyte count) of AIDS patients with disseminated NTM disease and non-disseminated NTM disease are different, while the prognosis is not significantly different.

Clinical epidemiological characteristics and prognostic risk factors in 2 245 patients with hemorrhagic fever with renal syndrome / 中华传染病杂志

Objective:To analyze the clinical epidemiological characteristics and the prognostic risk factors of patients with hemorrhagic fever with renal syndrome (HFRS).Methods:A total of 2 245 HFRS patients who were admitted to the Second Affiliated Hospital of Air Force Medical University from September 2008 to December 2021 were enrolled. Clinical epidemiological data (including gender, age, onset season, onset region, case fatality rate, et al) of HFRS patients were analyzed. The clinical epidemiological characteristics of patients with HFRS in the 2008 to 2012, 2013 to 2017, and 2018 to 2021 groups were compared. Statistical comparisons were performed using chi-square test. The Bonferroni adjusted P-value method was used for pairwise comparisons between groups, and logistic regression analysis was used to screen and evaluate the risk factors associated with the prognosis of HFRS patients. Results:The age of 2 245 HFRS patients was (42.3±15.9) years old. Most of them were male (79.24%(1 779/2 245)), and the main incidence area was Xi′an City (69.53%(1 561/2 245)). There were 132 deaths with an overall case fatality rate of 5.88%. There were 1 088 patients (48.46%) from 2008 to 2012, 647 patients (28.82%) from 2013 to 2017, and 510 patients (22.72%) from 2018 to 2021, with a mortality rate of 7.17%(78/1 088), 5.10%(33/647) and 4.12%(21/510), respectively. From 2008 to 2021, both the number of HFRS cases and the case fatality rate had shown a fluctuating downward trend. There were significant differences in case fatality rate, age distribution, onset season, and onset region among patients in the different year groups ( χ2=6.84, 49.22, 83.47 and 19.29, respectively, all P<0.05). The results of pairwise comparisons showed that the proportion of patients aged >60 years in the 2018 to 2021 group (23.33%(119/510)) was higher than those in the 2008 to 2012 group (12.13%(132/1 088)) and the 2013 to 2017 group (12.36%(80/647)), and the differences were statistically significant (both P<0.05). The proportions of patients at large peak (October to December) were 62.35%(318/510) in the 2018 to 2021 group and 56.26%(364/647) in the 2013 to 2017 group, which were both lower than that in the 2008 to 2012 group (75.18%(818/1 088)), and the differences were both statistically significant (both P<0.05). The case fatality rate of patients aged >60 years was 9.67%(32/331), which was higher than those of patients aged <30 years (2.86%(16/559)) and patients aged 30 to 60 years (6.20%(84/1 355)), with statistically significant differences (both P<0.05). Univariate analysis showed that age 30 to 60 years, age >60 years, smoking, complicated with hypertension, hypotensive shock and hypoxemia were significantly correlated with the prognosis of HFRS patients (odds ratio ( OR)=2.243, 3.632, 1.484, 3.532, 79.422 and 143.955, respectively, all P<0.05). The results of multivariate logistic regression analysis indicated that complicated with hypertension ( OR=2.467, P=0.004), hypotensive shock ( OR=11.658, P=0.001), and hypoxemia ( OR=67.767, P<0.001) were the independent risk factors affecting the prognosis of HFRS patients. Conclusions:The prevalence of HFRS has shown new changing characteristics from 2008 to 2021. The numbers of HFRS patients and the case fatality rates show a downward trend, and the proportion of HFRS patients aged >60 years increases. Complicated with hypertension, hypotensive shock and development with hypoxemia are the independent risk factors for the prognosis of HFRS.
